Heads held by endermen are invisible

Relates to MCPE-239735, MCPE-239737, MCPE-243593, MCPE-243611, MCPE-243612 and MCPE-243613.

If an enderman holds any type of head, its arms will be bent forward in a holding position, but the contents of those arms cannot be seen at all.

To reproduce:

• spawn an enderman

• run the command /replaceitem entity @e[type=enderman] slot.weapon.mainhand 0 skeleton_skull

Command for Java Edition, where this bug does not happen: /summon minecraft:enderman ~ ~ ~ {NoAI:1,carriedBlockState:{id:"skeleton_skull"}}

Expected results: a skull in the enderman’s hands.

Actual results: a nothing in the enderman’s hands.
